概括

这项研究发现,将Assure Plus®与Pro Seal®用于正牙支架粘合的结合,产生了与Assure Plus®单独相比的剪接强度 (SBS). 这两种方法都超过了临床值,表明了可接受的临床性能.

科学领域:

牙科材料科学牙科材料科学
ортодонтическая粘附技术 ортодонтическая粘附技术是指牙的粘附技术.

背景情况:

ортодонтика支架粘合依赖于可靠的粘合系统.
艾瑟普拉斯 (Assure Plus®) 是一种常见的粘合剂,而Pro Seal®有时被用于辅助,特别是在非典型的面膜表面上.

研究的目的:

为了比较单独使用Assure Plus®和Assure Plus®与Pro Seal®结合的牙科支架的剪接强度 (SBS).
为了评估脱后的粘合剂残留指数 (ARI),以评估粘合失败模式.

主要方法:

一个体外研究使用了42个提取的人类前牙.
牙被随机分配到两个组:Assure Plus® (控制) 和Assure Plus®与Pro Seal® (测试).
在37°C保存24小时后测试了剪接键强度;曼-惠特尼U测试分析了数据 (α=0.05).

主要成果:

平均SBS为Assure Plus®的11.20±2.51MPa和组合组的10.62±3.56MPa,没有显著差异 (P=0.094).
两组都超过了临床上可接受的SBS范围6-8MPa.
粘接残留指数 (ARI) 得分相似,主要表明粘接失败,牙上留下了大量的粘接剂.

结论:

通过将Pro Seal®与Assure Plus®结合起来,可以显示出与单独的Assure Plus®相比的债券强度.
这种联合方案在临床上是可接受的,用于正统牙科支架粘合,特别是在非典型的牙上.
这些发现支持使用Assure Plus®与Pro Seal®作为可行的临床结合选择.

Bonding and Strength of Aggregate

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...
